PIPE-STOPPER.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed June 14, 1910. Serial No. 566,850.

To all whom it may concern:

Be it known that I, FREDERICK AUGUSTUS KIRK Coon, a subject of the King of Great Britain, residing at London, England, have invented certain new and useful Improvements in Pipe-Stoppers, of which the following is a specification.

My invention relates to improvements in pipe stoppers for pressing tobacco into a pipe bowl; and the object of my improvement is to provide a tobacco presser which will press the tobacco into a pipe bowl after being filled so that the pipe will draw comfortably, and especially to achieve this without displacing the tobacco. I attain this object by the device illustrated in the accompanying drawing, in which:

Figure l, is a sectional elevation showing the piercer retracted; Fig. 2, is a similar view showing the piercer projecting; Fig. 8, is a plan view showing the hinged lid open; Fig. 4c, is a detail view of the piercer; and Fig. 5, shows a modified form of cap.

Referring first to Figs. 1, 2, 3, and 4, a is a casing provided about midway of its length with a division plate I), perforated centrally for the passage of the shank 0 attached to the disk cl, which disk in turn carries the four outer prongs e and the longer central prong f, in addition the disk also carries the two guide pins 9 which pass through corresponding holes in the plate Z) for the purpose of guiding the prongs so as always to return through the holes 71. in the lid 2'; the lid 2' is hinged at 7: by a hinge presenting eXterio-rly no projection beyond the circle of the casing a, and it is fastened by a snap fastening also having no projecting parts. The disk 0? Figs. 8 and 41 is cut out to allow room for the hinge 72 if necessary.

The complete piercer, as in Fig. 4, is in serted when the cap 71 is open and before aflixing the top Z the spring on is placed over the shank 0 and compressed between Y the top and the division I). The top is preferably attached to the shank c by a washer and a ring a, but may of course be soldered thereto if a plain top is required.

When the device is in use the end 2' is pressed on the tobacco in a pipe bowl and by depressing the top Z the piercer prongs are caused to enter the tobacco beneath the end 2' and make draft holes therein.

The top Z is guided by the casing m, and

i preferably abuts against the division plate Z) at the end of its travel so as to limit the amount of projection of the prongs e, f

The guide pins 9, g, may be integral with two of the piercer prongs if desired.

Fig. 5 shows an alternative to the hinged end i, the sliding cap j being fitted so as to retain its position even in use, and being kept always in correct position for the passage of the prongs through its perforations by the guide hump 0 working in the slot p.

It is clear that in use there must always be a perforated end disk to press on the tobacco while the piercer is being projected into the tobacco otherwise it will not be possible to retract the piercer without displacing the tobacco.

What I claim as my invention and desire to secure by Letters Patent, is

1. The combination in a pipe stopper of a casing, a pressing disk thereon having a number of perforations in its surface, a piercer having a number of prongs corresponding to the number of perforations, and means for projecting the piercer prongs through the perforations of the disk while the latter is in contact with the tobacco, all substantially as set forth.

2. The combination in a pipe stopper, of a casing having a fixed division plate and a perforated base, with a spring operated piercer working through a hole in the division plate and having a plurality of prongs working through the perforations of the base, substantially as described.

3. The combination in a pipe stopper, of a casing having a fixed division plate, a perforated base to the casing, a piercer within the casing having a plurality of prongs located opposite the perforations of the casing base, a shank on the piercer working through a hole in the division plate, a presser cap on the said shank, a spring operating between the division plate and the presser cap, and means for guiding the piercer so that its prongs always enter the perforations of the casing base when proj ected, all substantially as set forth.

4. In a pipe stopper, the combination of a casing having a fixed division plate, a perforated base hinged to the casing, a piercer within the casing having a plurality of prongs located opposite the perforations of the casing base, a shank on the piercer working through a hole in the division plate, a presser cap on the said shank, a spring operating between the division plate and the presser cap, and means for guiding the piercer so that its prongs always enter the perforations of the casing base when projected, all substantially as set forth.

5. In a device of the kind described, a cylinder, a perforated division plate in said cylinder a disk movable therein, a piercer carried by said disk, and guide pins carried by the disk and working through the division plate, as and for the purpose set forth.

6. The combination in a pipe stopper, of a casing having a fixed division plate, a perforated base hinged to the casing, a piercer within the casing having a plurality of prongs, a shank and guide pins on the piercer passing through holes in the division plate, a presser cap on the shank which fits within the casing and abuts against the division plate to limit the projection of the piercer, and a spring between the division plate and the presser cap, all substantially as set forth.

In testimony whereof I have afiixed my signature in presence of two witnesses.
